Description 

Galvanized Girder bridge, skewed nearly 45 degrees to RR. Bridge is also at an angle to the road, turning sharply to the right as you come downhill. This makes the bridge nearly a blind corner all by itself.

Bridge shows no signs of rusting. Timber deck is in great shape. Side channels are bolted together, not welded. The train tracks are said to be abandoned, but appear to be in excellent and usable condition.

Whatever the 1852 bridge was, it is completely gone.
